I have Exchange 2010 server. Today Windows server backup took a long time completing "checking exchange database consistency check" than usual although the backup is running currently after completing consistency check. So I checked two exchange mailbox database folders. In one/first database folder, I have 4,149 log files. In another/2nd database folder, I saw 17,161 log files. Out of that,15,241 were created on 12/17/2017. Fyi, I began moving a mailbox on afternoon of 12/16/2017 from first database to 2nd database which was completed at the night of 12/18/17.
Also I noticed that Windows Server Backup has not run since 12/17/2017 until today. I tried to start the backup manually, but failed, After rebooting server, it began backing up after long consistency check.
Is it normal to have this many log files? Did the mailbox move create this many log files?
Should I leave them alone or do something to purge them?
